Answer 3

Hint: A positive number can also include rational numbers (4/11, 31/29, etc), and irrational numbers such as sqrt(2), pi, e, etc.

Answer 4

It can't be all positive numbers, because that includes non-integers (1/2, 3/4, etc.)

It isn't the second or first one, because there are integers greater than 5, and greater than 100 (101, 102, etc.)

Answer 5

Its the last one {1,2,3,4,5...}
